Description
본 고안은 배기가스정화용 촉매컨버터에 관한 것으로, 더 상세하게는 모든 배기가스가 촉매를 거치는 것에 의해 우수한 정화율을 얻을 수 있도록 고안된 것이다.The present invention relates to a catalyst converter for purifying exhaust gases, and more particularly, to devise an excellent purification rate by passing all the exhaust gases through a catalyst.
일반적으로 자동차에는 배기가스 정화를 위해 배기매니홀드의 배출구와 머플러 사이에 촉매컨버터가 설치된다.In general, a catalytic converter is installed between an exhaust port of an exhaust manifold and a muffler for exhaust gas purification.
현재 사용되고 있는 촉매컨버터는 케이스를 형성하는 쉘(10)과, 모노리스(20) 그리고 이 모노리스(20)를 감싸는 매쉬(30)로 구성된다.The catalytic converter currently used is composed of a shell 10 forming a case, a monolith 20 and a mesh 30 surrounding the monolith 20.
이때 쉘(10)과 매쉬(30)는 부식을 방지하기 위해 스테인레스재로 성형되고 모노리스(20)는 허니컴상태로 그 외부를 매쉬(30)가 보호하여 충격을 막아주는 것이다.At this time, the shell 10 and the mesh 30 is formed of stainless material to prevent corrosion, and the monolith 20 is a honeycomb state to protect the outside of the mesh 30 to prevent the impact.
종래, 촉매컨버터의 구성에 의하면 허니컴모노리스(20)를 감싸는 매쉬(30)가 단순히 스테인레스스틸로 구성되어 있어 이부분을 통과하는 배기가스는 전혀 정화가 되지 않고 배출되는 단점이 있다.Conventionally, according to the configuration of the catalytic converter, the mesh 30 surrounding the honeycomb monolith 20 is simply made of stainless steel, so that the exhaust gas passing through this portion is discharged without being purified at all.
즉, 허니컴 모노리스(20)를 통과하는 배기가스는 거의 정화가 이루어져 무해한 가스가 되는 반면, 그 외벽은 워시코팅이 전혀 안되어 있는 코디에나이트와 같은 세라믹으로 구성되어 있다.That is, while the exhaust gas passing through the honeycomb monolith 20 is almost purified to be a harmless gas, the outer wall is made of ceramic such as cordierite, which is not coated at all.
따라서, 일단 스테인레스스틸로 된 매쉬(30)로 들어간 배기가스는 매쉬(30) 내에서 플로우(FLOW)를 일으켜도 허니컴 모노리스(20)로 들어가 정화되기 어렵다.Therefore, the exhaust gas once entered into the mesh 30 made of stainless steel is difficult to enter the honeycomb monolith 20 and purify even if a flow occurs in the mesh 30.
한편, 두 베드형 허니컴 모노리스(20) 타입의 경우에는 스테인리스스틸 쉘(10) 중간턱에 의해 일부가 두번째의 모노리스(20)로 들어가는 경우도 있지만 이는 극히 적인 양이므로 두번째 모노리스(20)의 매쉬(30)를 통과하는 배기가스는 정화없이 배출된다.On the other hand, in the case of the two-bed honeycomb monolith 20 type, a part of the second monolith 20 may enter the second monolith 20 by the intermediate jaw of the stainless steel shell 10, but since this is an extremely small amount, the mesh of the second monolith 20 Exhaust gas passing through 30 is emitted without purification.
그러므로 대기로 CO, HC, NOX를 일부 정화없이 배출되어 그 정화율이 저하되는 등의 폐단이 있었던 것이다.Therefore, CO, HC, NO X were discharged to the atmosphere without some purification, and the purification rate was lowered.

이러한 본 고안의 목적은, 케이스를 형성하는 쉘(10)과 이 쉘(10)의 내부에 대부분의 배기가스를 정화시키는 허니컴 모노리스(20)와 이 모노리스(20)를 감싸는 스테인레스스틸 매쉬(30)로 구성된 것에 있어서 상기 매쉬(30)에 귀금속의 워스코트를 코팅하는 것에 의해 달성된다.The object of the present invention is a shell 10 forming a case and a honeycomb monolith 20 for purifying most of the exhaust gas inside the shell 10 and a stainless steel mesh 30 surrounding the monolith 20. It is achieved by coating a scouring of precious metal on the mesh 30 in the configuration.
상기한 본 고안에 의하면, 스테인레스스틸 매쉬(30)를 통과하는 배기가스도 정화되므로 촉매역할에 의해 보든 유해가스를 정화시킬 수가 있는 것이다.According to the present invention described above, since the exhaust gas passing through the stainless steel mesh 30 is also purified, it is possible to purify all harmful gases by the catalytic role.
이하, 첨부된 도면에 의거하여 본 고안의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1 은 촉매컨버터의 구성을 도시한 것으로, 쉘(10)과, 허니컴 모노리스(20)와, 매쉬(30)로 구성된 것을 도시하고 있다.FIG. 1 shows the configuration of a catalytic converter, and shows a shell 10, a honeycomb monolith 20, and a mesh 30. As shown in FIG.
상기 쉘(10)은 케이스를 형성하여 그 내부로 대부분의 배기가스를 정화시키는 허니컴 모노리스(20)를 수용하는 것이며, 이 모노리스(20)의 외부를 스테인레스스틸 매쉬(30)로 감싸지게 구성되는 것은 종래와 동일하다.The shell 10 is to accommodate the honeycomb monolith 20 to form a case to purify most of the exhaust gas therein, the outside of the monolith 20 is configured to be wrapped with a stainless steel mesh (30) Same as before.
본 고안의 가장 중요한 구성상의 특징은 상기 매쉬(30)에 귀금속의 워스코트를 코팅하는 것에 의해, 정화를 위해 모노리스(20)를 통과할 때 반드시 거쳐야 되는 매쉬(30)에 의해서도 촉매에 의한 정화가 이루어 지도록 하는 것이다.The most important structural feature of the present invention is by coating the scotch of the precious metal on the mesh 30, the purification by the catalyst is also required by the mesh 30 that must pass through the monolith 20 for purification. To be done.
이때, 매쉬(30)에 코팅되는 귀금속의 워스코트는 파나듐(Pd) 및 파나듐(Pd) + 백금(Pt), 백금(Pt) + 로듐(Rh), 파나듐(Pd) + 백금(Pt) + 로듐(Rh)이 주로 사용된다.At this time, the precious metal coated on the mesh 30 is Panadium (Pd) and Panadium (Pd) + Platinum (Pt), Platinum (Pt) + Rhodium (Rh), Panadium (Pd) + Platinum (Pt) ) + Rhodium (Rh) is mainly used.
따라서, 이 매쉬(30)를 통과하는 배기가스가 상기한 귀금속의 워스코트에 의해 촉매역할로 CO, HC, NOX를 동시에 정화시켜 배출을 저감시키는 것이다.Therefore, the exhaust gas passing through the mesh 30 simultaneously purifies CO, HC, and NO X by the catalytic role of the above-described Worscote of the precious metal to reduce the emission.
도 3 은 종래 스테인레스스틸재로만 된 매쉬(30)의 내부로 허니컴 모노리스(20)가 형성된 상태로 점선으로 도시한 바와 같이 중앙의 모노리스(20) 부위에서만 정화되는 상태를 보이고 있다.3 shows a state in which the honeycomb monolith 20 is formed inside the mash 30 made of stainless steel only, and is purified only at the center monolith 20 portion as shown by a dotted line.
도 4 는 본 고안의 특징에 의해 매쉬(30)가 귀금속의 워스코트가 부착된 상태로 매쉬(30)를 통과할 때 정화가 이루어 지므로 전체적으로 고르게 모든 배기가스가 정화되는 것을 도시하고 있다.Figure 4 shows that all the exhaust gas is evenly purified as a result of the purification is made when the mesh 30 passes through the mesh 30 with the wosco of precious metal attached to it by the features of the present invention.
이상에서 설명한 바와 같이 본 고안에 의하면, 모든 배기가스가 정화되므로 유해 CO, HC, NOX를 동시에 정화시켜 배출을 저감시키는 것이다.As described above, according to the present invention, since all exhaust gases are purified, harmful emissions are reduced by simultaneously purifying harmful CO, HC, and NO X.
따라서, 정화율이 향상되는 등의 매우 유용한 고안인 것이다.Therefore, it is a very useful design such that the purification rate is improved.
본 고안의 목적은 매쉬를 통과할 때도 정화가 이루어져 모든 배기가스가 정화를 거치는 것에 의해 그 정화율이 향상될 수 있도록 한 촉매컨버터를 제공하는 데 있다.It is an object of the present invention to provide a catalytic converter in which purification is performed even when passing through a mesh so that the purification rate can be improved by passing through all the exhaust gases.
